Pop me your email and I can forward you a copy of the board cad file. I should find a place to host it publicly. Any ideas? Don't think the forum has a file host function does it?
Won't be IKA production compliant but you don't have to wait on a list.
If you want to make it lighter scale it down 1/4 inch and bag on some 1/8 closed cell foam. Next board I do will be sandwich. Oh and don't fall for the temptation of sanding the rails with the rotary disk sander. You will inevitably burn through the rail at the transition between round and hard edge just in front of the fins. I just cut that section out and fixed it.
All props to Gary Menk. His sight has good written instructions on a similar build.
